As previously announced, Madonna will headline the Bridgestone Super Bowl XLVI Halftime Show. "It's the most nerve-racking thing I've ever done," the 53-year-old Material Girl said on The Tonight Show With Jay Leno. "The Super Bowl is like the Holy of Holies of America. I have to go on in the middle of that Holy of Holies and put on the greatest show that was ever put on before."
